Stakeholders are demanding nonprofit organizations (NPOs) continually improve and work effectively in an ever-changing environment. While there are many ways to approach this operational challenge, this paper examines the impact of acquiring an accountability certification, specifically the Standards for Excellence® Certification. Using a sample of 102 NPOs that have received the Standards for Excellence certification, we find that the certification is associated with increases in public support relative to a control group that did not receive the certification. These results suggest that some stakeholders favorably respond to the certification process, and NPOs can realize tangible benefits from becoming certified.  相似文献

A study was conducted to compare the interpretive and coping responses of female and male survivors of incest and female survivors of sexual assault by a nonrelative. Twenty-eight persons responded to a questionnaire that asked them to provide an account of the nature of an assault(s), the role of confidants in helping them cope with the assault, how they coped and tried to understand the assault over time, how they felt the assault affected their close relationships, and how they evaluated their current state of recovery. The results for male and female incest groups were similar in revealing great difficulty in coping and in having adult close relationships. These two groups showed more continuing lack of resolution than did the female nonfamilial survivors. The male group of incest survivors showed the greatest overall difficulty. The findings are discussed in terms of the roles of searching for meaning via account-making and confiding as ways of dealing with long-term, major Stressors in people's lives.  相似文献

Correctional staff job burnout is costly to all involved. As such, it has generated a growing body of research. This study reviewed 53 empirical studies of correctional staff burnout and two review articles published between 1981 and 2014. The majority of studies focused on staff working in a variety of institutional positions, fewer studies focused exclusively on the subgroup of correctional officers, and even fewer focused on a different subgroup. The majority of studies also involved staff at US government-run adult prisons. Most but not all studies utilized Maslach’s Burnout Inventory. Research on the antecedents of job burnout among correctional staff is more common than research on the possible consequences or outcomes of job burnout. Interestingly, despite the empirical emphasis on antecedents of burnout, there has been almost no research on effective interventions designed to deal with correctional staff burnout. Based on this narrative review, significant gaps remain in the research on correctional staff burnout.  相似文献

Since 2006, hundreds of communities in Canada have produced Integrated Community Sustainability Plans, based on a four-pillar model of sustainability and developed in consultation with residents and stakeholders. These community-based experiments have developed models, knowledge, and insights about the place of culture in local sustainability. Both conceptual thinking and planning practices regarding the role of culture in sustainable communities were at an embryonic stage when these initiatives took place. The discussions, plans, and implementation processes have advanced both theory and “leading edge” practices with regard to culture and community sustainability, illustrating the importance of a robust relationship between research and practice.  相似文献

Significant efforts are being devoted to the development of methods enabling rapid generation of short tandem repeat (STR) profiles in order to reduce turnaround times for the delivery of human identification results from biological evidence. Some of the proposed solutions are still costly and low throughput. This study describes the optimization of an analytical process enabling the generation of complete STR profiles (single‐source or mixed profiles) for human identification in approximately 5 h. This accelerated process uses currently available reagents and standard laboratory equipment. It includes a 30‐min lysis step, a 27‐min DNA extraction using the Promega Maxwell®16 System, DNA quantification in <1 h using the Qiagen Investigator® Quantiplex HYres kit, fast amplification (<26 min) of the loci included in AmpF?STR® Identifiler®, and analysis of the profiles on the 3500‐series Genetic Analyzer. This combination of fast individual steps produces high‐quality profiling results and offers a cost‐effective alternative approach to rapid DNA analysis.  相似文献
